The article attempts to bridge semiotics with species conservation and management. Biosemiotic and cultural semiotic methodology is applied in the analysis of a case study – the early occurrence of the golden jackal in Estonia. Nine semi-structured interviews were carried out with the local inhabitants of the Matsalu region, professional zoologists and environmental officials who were involved in the golden jackals’ discourse. The interviews were analyzed for interactions between golden jackals and humans, expected ecological effects of golden jackals, communication between (...) different interest groups and central cultural motifs used to interpret the new species. It is argued that in the development of this discourse, the golden jackals’ own activity has played an essential role. At the same time, human cultural models also influence the interpretation of a new species to a considerable degree. Two of such models – the opposition of the own and the alien and the “settler’s” narrative – are brought out and analyzed. The effect of the fear of the unknown is also specified. To improve human communication about new or invasive species, it is suggested to raise awareness of the underlying cultural models and to use integrative communication as the developing discourse is dynamical and constantly changing for all interest groups. For a semiotic study of species management, it is suggested to combine methodology from biosemiotics, cultural semiotics and actor-network theory. (shrink)

Jakob von Uexküll’s umwelt theory opens new perspectives for understanding animal extinction. The umwelt is interpreted here as a sum of structural correspondences between an animal’s subjective experience, ecosystem, physiology, and behaviour. The global environmental crisis disturbs these meaning-connections. From the umwelt perspective, we may describe extinction as umwelt collapse: The disintegration of an animal’s umwelt resulting from the cumulative errors in semiotic processes that mediate an organism and ecosystem. The loss of umwelt-ecosystem integration disturbs “ecological memory,” which provides the (...) ecosystem with adaptive modelling and self-design capacities. Making a distinction between core and mediated umwelts, and describing different types of umwelt collapse, are suitable methods for more detailed analysis. The concept of umwelt collapse enables the reinterpretation of extinction, from an internal perspective, as a semiotic breakdown. Such an approach may help us map scenarios of animal extinction, and may lead to successful compensation strategies in adapting to environmental change. (shrink)

A new approach to landscape ecology involves the application of the eco-field hypothesis and the General Theory of Resources. In this study, we describe the putative eco-field of bark beetles as a spatial configuration with a specific meaning-carrier for every organism-resource interaction. Bark beetles are insects with key roles in matter and energy cycles in coniferous forests, which cause significant changes to forestry landscapes when outbreaks occur. Bark beetles are guided towards host trees by the recognition of semiotic signals using (...) a specific eco-field. These signals mainly comprise a group of scents, which are called the odourtope. Their interactions with other organisms occur by sharing relevant information from the eco-field networks in the forest ecosystem. The eco-field networks modulate the expansion of the realized semiotic niche of the bark beetle towards the potential semiotic niche. Moreover, the niche construction process can be initiated by interchanging signals among species living in the same place, where these signals allow the exploitation of the required resources. If different organisms are interdependent on signals in eco-field networks, then this process may result in the establishment of mutualistic relationships. This is an example of how evolutionary processes are initiated by the recognition of signals in a network of eco-fields. (shrink)

Describing resources and their relationships with organisms seems to be a useful approach to a ‘unified ecology’, contributing to fill the gap between natural and human oriented processes, and opening new perspectives in dealing with biological complexity. This Resource Criterion defines the main properties of resources, describes the mechanisms that link them to individual species, and gives a particular emphasis to the biosemiotic approach that allows resources to be identified inside a heterogeneous ecological medium adopting the eco-field model. In particular, (...) this Criterion allows to couple matter, structured energy and information composing the ecological systems to the biosemiotic and cognitive mechanisms adopted by individual species to track resources, transforming neutral surroundings into meaningful species-specific Umwelten. The expansion of the human semiotic niche that is a relevant evolutionary process of the present time, assigns the role of powerful and efficient agency to the Resources Criterion to evaluate the effect of human intrusion into the natural systems with habits of key stone species, under the challenge of a growing use of alloctonous, immaterial and symbolic resources of the actual globalized societal models. The Resource Criterion interprets the ecological dynamics contributing to complete the epistemology of the ecology, to open a bridge toward economy and other societal sciences, and to contribute to formulate a General Theory of Resources.

An ecological description of a landscape transcends its geographical definition to characterize it in terms of a complex agency composed of a spatial mosaic, structured energy, information and meaning. Because the dimensions of the landscape encompasses both natural and human processes, it requires a more robust set of theories that incorporate the material components and their perceptual meaning. A biosemiotic approach defines the landscape as the sum of its organisms’ eco-fields, which are spatial configurations that carry meanings connected to specific (...) needs and related functions. In this perspective, the new postulated General Theory of Resources, offers a substantial contribution to complete the paradigmatic framework of a “private landscape” species-, individual- and function-specific. From this theory resources are considered every material (f.i. food) or immaterial elements (f.i. safety) necessary to fullfill individual needs. The habitat becomes the “private landscape” and the well-being versus the ill-being are the emergent conditions of each individual under the environmental constraints. Definitively space is the entity on which material and immaterial resources are distributed and the dimension on which individuals species are interacting by using biosemiotic mechanisms. (shrink)
